Slow Day (with Quiz #2)

Unexpectedly, and unfortunately, the last time out birding turned out to be a slow day. It seems as though many of the migrating birds may have already passed through the area, or maybe the amount of sun was keeping a lot of them down. Either way, it was the 1st time in a month that I didn't see a single Warbler. On the plus side, I got great looks at both Red-eye and Warbling Vireos. I recorded a few of their "voices", some of which might appear in later quizzes, but not the one this week. Bird vocalizations can be roughly sorted into two groups, Songs and Calls. Songs are almost always done by males and usually are used to claim territory or find a mate. Calls serve other various functions. David Sibley's book, Birding Basics, will tell you everything you need to know about bird vocalizations--and about everything else birding too. Let me know what you think after you listen to Quiz #2.
